That has been talked about. It’s an extremely time consuming process which will need frame by frame editing. I’ve love to have Rey in black to represent her in morning for Luke & Leia and actually have her outfit significantly change for once but I’m still working on the crackling Saber plus Palpatines red lightning which is taking forever. If someone else has the skills to do this well I’d be happy to help but can’t take on anymore scenes atm.
That’s understandable, I wasn’t really asking anyone to do it for me - I was just wondering if whoever made the mockup had some kind of software or HSB preset that would make it easier if I were to give it a try.
